This can be in the form of being on our screens too much before bed, drinking alcohol before bed or even exercising late at night. Poor sleep hygiene habits and external sensory stimulants contribute to sleep restlessness in a variety of ways.
If you’re on your phone or watching Netflix late into the night right before you go to sleep, the blue light coming off of these screens could delay your body’s natural sleep inducing hormone, melatonin. Along the same lines, if you have too much noise or light coming into your sleep environment, your senses will be energizing when they need to be relaxing. Then if you’re eating too late or consuming caffeine, alcohol or other stimulants, then your sleep cycle will be thrown off.
